"The council will take forward some work to explore appropriate targeted responses in light of what has happened in Danish territory."

The measures could include adopting at EU level the sanctions France imposed last month on two suspected Iranian agents and others from Iran's ministry of intelligence and security.

France's security services concluded that the head of operations at the Iranian intelligence ministry had ordered a plot to bomb a rally of the People's Mujahedeen of Iran (MEK) opposition group in a suburb of Paris in June.

Iran has been blamed in the past for attacks in countries as far afield as Argentina, India and Thailand, and French officials say Tehran is also suspected of carrying out "several" assassinations of opposition figures in Europe since 2015.
